SJ145-4 Mikuni main jet N102-221, size 145

Precision is everything when it comes to carburetor jetting, and these EBC main jets deliver exactly that. Manufactured by A-BAX Precision Engineering, this size 145 jet is a direct replacement for the Mikuni N102-221 series. These jets are designed to fit a variety of Mikuni carburetors, including the HS40 and the HSR42, HSR45, and HSR48 smoothbore units often used on performance-oriented bikes. They are also compatible with BSR, SV650, and BN series carbs such as the BN38, BN44, and BN46I. Sold as a pack of four, they provide the consistency needed for a professional tune-up. If you are looking to increase fuel flow for a high-flow intake or performance exhaust, these jets offer the reliable accuracy required to keep your engine running at its peak.
